That damned Sun family
Once the knife was heated up nicely Yu Dong turned her attention back to Sun Jie's daddy and then placed her hand on his back before she released calming spiritual energy from the tips of her fingers such that Wang Ergou would not feel any pain at all. The last time she scraped her flesh was when she was in the apocalypse world and was working as an officer, even she felt like her entire body was set on fire when she had to chop a part of rotten flesh out of her body which was why she was completely aware of the fact that Wang Ergou who was a mer would not be able to take the pain.
This was why she released her spiritual energy to make sure that Wang Ergou would not feel any pain and that her energy will block the pain that he was feeling at the moment along with the one she was going to deliver any second now.
